in New York, ot A\ew Yorlnhavc invented certain n ew and usefulImprovements 1n Igiting Attachments for Burners, of which thet'ollowingis a speci- `ticat1on. i

lt is well known that when a current of combustible gas impinges againstplatinum sponge the sponge is brought-'to incandescence and thcgasignited thereby. It has been proposed to arrange such platinum sponge inthe cen'- tral part of theincandescent mantle; but it.

has been found that with such an arrangement some time elapses b etoreignition takes place and that a consitlerablequantity of g-asA gathersin e' upper `vand loweivparts of the mantleswhich'when thesponge isbrought to incandescence explodes, whereby the attendant concussionaccompanying theV ignition'ot' the gas causes an al'ipreciableA decreasein the life of the incandescent mantle and so aggravates the mainobjection# frequent renewal of the same.

This invention relates to ments for burners, and more particularly toigniting-caps which may be easily applied to any burner-tube, and whenonce applied .it is only necessary Ito turn the cock of the burner andso permita current of gas to impinge against aplatinum sponge suitablyattached to said cap and' in this manner ignite the rgas as Soon as itleaves" the burner, without the objectionable explosion accompanyingignition by matches, portable ignition devices, &c.

The object of" this invention is to obviate the objections abovereferred to by providing a device `which is easy to manufacture, simpleto apply, and commendable for general adaptation.

For this purpose the invention consists of an igniting-cap forincandescent gas-burners by a. current of combustible gas, as will beigniting attach'- i out in the claims.

In the accompan \"1ng drawings, F1gure1l i fullvdescribed hereinafter.and finally pointed Be itv known that I.

Referring to the drawings, A` represents a gas-burner provided withtheusual .air-openings- (tand with a chimney provided with :ur-openings7;' at its lower part. The burner is also provided with a rod/, which isverticallyadjustable by means of a screw d', which supports a'nincandescent mantle m. On the upper tubular part of the burner a isapplied `an igniting-cap R, which supports a platinum sponge I in thepath of the combustible gascurrent passing through the burner f. Theburner-tube f is provided at its upper part with the usual screen s. Theplatinum sponge I is incandesced when brought in Contact with thecombustible gas, which incandescence ignites the combustible gas, andso'lights the lamp without any portable ignition means, as matches,tapers, &c.

\ The igniting-cap R consists of a cylindrical part or sleeve n, made ofsuitable material, preferably sheet metal, the lower part of which isprovided with a part n-, of somewhatlarger dimension than the part n, soas to form a `shoulder n2, by means of which the sleeve n rests on theupper part of the tube f. The

upper part ot' the cylindrical sleeve n is provided with an annular partn3., in which is seated the top onsuspeiiding part of the cap.

.This top t is preferably made otmagnesium, clay, or othernon-combustible material, and

consists, essentially, of several radial parts t', `forming segmentalopenings .0 between the same and terminating in the central part t2,which 1s provided with atransverse pin 77, to

. which a platinum'wire 7,', with'a platinum sponge 1 suspended thereby,vis attached. The top t is also provided with a central opening t3, inwhich the mantle-supporting rod d can be placed when central support ofthesame is preferred. y

Very often' attachable caps provided w'ith screens are sold with theincandescent gas'- mantles and are not arranged in the burners,

asishown in Fig. 2. 1n applying my'irnproved igniting means tosaidburners it becomes necessary to arrange .the screen .s 1n the.ignitingcap R, as shown in Fig. 4, for which purpose l f the sleeve n isprovided with'an annular part a, in which the sleeve may rest. The capR, consisting of the'sleeve w and the' topt, may

' be formed in one piece-#in fact, it maybe any means attachable to theburner-tube andmay be made of any suitable material or shape con`forming to an efiicient operation, the main feature of the inventionbeing in. providinga portable attachment for burners easily manufacturedand complete in andforv itself lby means of which the gas may beignited.

My improved ignitingcap may be easily nianufactured and brought into themarket in the form shown in Fig@4 and maybe purchased ata small cost andapplied by any one to--the burners already in use or may be sold eitheras a separate cap orwith thev burners as a part integral therewith. y

The great disadyantage of gas-burners l which has caused many to adoptthe electric llight'--namely, the use ofl matches-is overcome'by myimproved igniting-cap, as it is only necessary by the use thereofl toturn the cock of the burner.V Matches are not only very often a sourceof inconvenience, but are also objectionable'on account of the danger offire attendant the use of thesame. Furthermore, when the gas-Jet of theimproved igniting-cap is accidentally' left open the gas emanating lWitnesses:

from the burner will immediately ignite, whereby the flame produced willgive knowl- Theignition of the gas will edge of the' fact.

have the further advantage that -the gas Will be ignited and burnedwhile emanating from the burner, and so remove the dangerof gasasphyxiation. When appliedto4 gas-burners .provided with incandescentinantles, the absence of explosions, lwith `attendant concussions,insures a longer life'to' the same, no

matches are required for its ignition, and all in= Jury caused byfalling matches' is obviated.

The igniting-cap being complete in and for 4itself forms an article ofmanufacture which 60 -may be produced 1n large quanftlties, so reducingthe cost of each cap correspondingly.

The improved igniti'ng-cap may beapplied vto.any burner by any onewithout requiring any changes inthe same, and may be.. due to itssimplicity, 'manufactured at a low cost, giving tlius ample reason forgeneral adoption. lclaim as new and desire to secureby LettersPatent- 1.
